306-020-420-158

Edgeboard Connectors Overview

The EDAC Inc. 306-020-420-158 is a dual-edge female card edge connector from the 306 Series, designed for panel and through-hole mounting. It features 40 positions arranged in two rows with a 0.156-inch (3.96mm) contact spacing. The connector utilizes cantilever contacts with gold plating over a thickness of 10.0µin (0.25µm). It accommodates PCBs with a thickness range of 0.054 to 0.070 inches (1.37mm to 1.78mm). The insulator is green thermoplastic polyester, and the unit operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with cantilever contact design for reliable board insertion
• Gold-plated contacts ensure stable electrical performance and corrosion resistance
• Thermoplastic polyester insulator body provides structural integrity and thermal stability
• Panel mount installation with flange features including top opening and threaded inserts

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard double-row connectors
• Test and measurement instrumentation boards
• General-purpose electronic assemblies needing high-reliability interconnects

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 40-position dual-edge specification. Confirm that the 0.156-inch pitch aligns with the target PCB layout. Ensure the operating temperature range of -40°C to 105°C meets environmental requirements. Check for RoHS compliance status if restricted substances are a concern. Validate that the panel mount style fits the mechanical enclosure constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.156-inch pitch is required. Consider the 306 series for applications needing panel-mount stability with through-hole termination. Evaluate the 40-position count against signal routing needs. Compare against single-edge variants if space or access constraints differ. Verify compatibility with the specified PCB thickness range of 1.37mm to 1.78mm.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 306 Series, which offers various position counts and contact spacings. The series is characterized by its low-profile insulator bodies and durable cantilever contacts. Similar parts in the family include different pin counts such as 14 or 20 positions, maintaining consistent mechanical and electrical standards across the lineup.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 306 series connectors with identical 40-position dual-edge specifications. Cross-reference compatible parts from manufacturers offering equivalent 0.156-inch pitch card edge connectors. Ensure mechanical dimensions and mounting styles match before substitution.
